Abstract
[DE] Die Erfindung betrifft eine Herz-Lungen-Maschine umfassend ein Kardiotomiereservoir und einen Oxygenator, in welchem eine Blutpumpe angeordnet ist, wobei das Kardiotomiereservoir direkt am Oxygenator angeordnet ist und der Blutausgang des Kardiotomiereservoirs in den Bluteingang der Blutpumpe mündet, bei der das Kardiotomiereservoir (1) unterteilt ist in ein oberes Notfallvolumen (2) und ein unteres Arbeitsvolumen (3), wobei das Arbeitsvolumen (3) ausgebildet ist durch einen Kanal (4), dessen oberes Ende (4a) in das Notfallvolumen (2) und dessen unteres Ende (4b) in den Bluteingang (10) der Blutpumpe mündet und der in einem transparenten unteren Abschnitt (1a) des Kardiotomiereservoirs (1) liegt, welcher oberhalb und ausserhalb des Oxygenators (9) angeordnet ist, so dass der Füllstand des Blutes in diesem Kanal (4) visuell erfassbar ist.
[EN] The invention relates to a heart-lung machine comprising a cardiotomy reservoir and an oxygenator in which a blood pump is disposed, wherein the cardiotomy reservoir is disposed directly on the oxygenator and the blood exit of the cardiotomy reservoir empties into the blood entry of the blood pump. The cardiotomy reservoir (1) is divided into an upper emergency supply (2) and a lower working supply (3), wherein the working supply (3) is formed by a channel (4), the upper end (4a) of which empties into the emergency supply (2) and the lower end (4b) of which empties into the blood entry (10) of the blood pump and that is located in a transparent lower section (1a) of the cardiotomy reservoir (1) disposed above and outside of the oxygenator (9) such that the fill level of the blood in said channel (4) may be ascertained visually.
